 The drawing of green laser pointer was mainly discussed.
This theory is that the atomic composition of the material, a different number of particles (electrons) are distributed in the different energy levels of particles in the high energy level by a photon excitation, jump from high energy level (transition) to the low energy level, then will radiate excitation light of the light of the same nature in a particular state, a low light to stimulate the phenomenon of a light. This is called by the stimulated emission of light amplification, referred to as laser. Laser there are four main features: laser high brightness, high directionality, high monochromaticity and coherence. The high brightness of the laser: the brightness of solid-state lasers can be as high 1011W/cm2Sr. Not only that, with high-intensity laser beam focused by a lens. Repair of green laser pointer has been finished.
So this is a high-speed rapid prototyping technology. Parts the greater the volume, the higher the efficiency. Processed parts can be used directly, without the need for correction. Without the need to design and build the support structure. Easy to use, and pollution-free. Disadvantages: less the type of practical application of raw materials, although the choice of certain raw materials such as paper, plastic, clay and synthetic materials, but the common paper, foil material suppliers in the research and development. The paper part is easy to absorb moisture, must be carried out immediately after processing, painting. Difficult to build the fine shape of the parts, is limited to the simple structure of the parts. This is the technical detail in the drawing of cell phone jammer .Each deposited overlying layer of paper, roll on by a hot pressing on the back of the paper, bonding or the first layer of paper on the platform. When the laser beam to be cut along the outline of the current layer. The laser beam accurate focusing, so just cut the thickness of the wear layer paper. The laser beam around the model and interior paper cut into small pieces so that the post-processing to remove these materials. In the molding process, these fragments can be a support the role model of cavity and cantilevered structures. In order to speed up the modeling process, each time cutting the second floor, or even three layers of foil materials. It is during the design liaison meeting of green laser pointer .
